EXPLORATION AND DEVELOPMENT

• Jurassic Prospect East Texas
  Generated a prospect covering approximately 10,000 acres based on subsurface control, seismic, offset production and a pre-fracture stimulation test in the key well. Apache Corporation acquired the property in 2002 and drilled and completed a well that has 65 feet of pay in the Cotton Valley Lime. Apache has drilled 6 wells in the area to date, 5 of which are successful completions in the Cotton Valley Lime, with potential pay behind pipe in the Cotton Valley and Bossier sands. Apache will spud a seventh well by the end of the 2nd quarter 2006. Apache controls over 7,000 acres on this prospect.
  
• Stockman Field Area - Shelby County, Texas
  Calvin was instrumental in negotiating an approximate 7,000 acre farm-out from a major independent oil & gas company. Calvin and its’ partners have re-entered 1 well and drilled 3 additional wells on this prospect, one of which has been completed in the Upper and Lower Cotton Valley sands. Two of the other wells are completed in the Travis Peak. An 11,000 foot well to test the Travis Peak and Cotton Valley sands is currently drilling.
  
• Upper Texas Coalbed Methane Project
  Calvin and its partner negotiated an exploration area agreement that covered over 3,500 square miles and built a database that incorporated geologic, geophysical, land and engineering data on several thousand wells. The database was used to develop multiple computerized maps and cross-sections that led to the drilling of a successful coalbed methane test in late 2000.
  
• Cedar Springs Prospect - Upshur County, Texas
  Generated 6,000 acre prospect which was based on the relation between pre-fracture stimulation flow test of Cotton Valley "Taylor" Sand interval in key well and proven producing interval in Cedar Springs Field. Sold prospect to Bannon Energy Corporation. Bannon utilized information in sale of 87.5% working interest in this prospect and Wright Mountain Prospect to Lomak Petroleum Inc. Bannon had capital expenditures of less than $2 MM for these two prospects and realized net gain of almost $8 MM from sale, including retention of a 12.5% working interest.
  
• Bald Prairie Field - Robertson County, Texas
  Evaluated the geologic, engineering and economic potential for acquisition of interests in 38 producing wells owned and operated by Dalen Resources. Integrated all data into report that was presented to Aquila Resources. Aquila subsequently made offer of approximately $13 million dollars to Dalen.
